| Graphics | anything on the page that is not actual text, from simple line drawings to fully active images found on the World Wide Web. There are many different graphic file formats. The format you choose depends on several factors. |
| Raster Graphics | Made of Pixles |
| Vector Graphics | Made of Lines and Shapes |
| Color Depth | The number of colors per pixel that can be contained in an image. Most graphics editing programs will allow you to set the color depth for your image. Different graphic formats contain different numbers of colors per pixel. |
| Compression | refers to how an image is saved in order to reduce the file size |
| Lossless | Reduces the file size without losing any pixel data Quality is not compromised |
| Lossy | Alters and/or eliminates some data The more the image is reduced, the more the quality is degraded |
| Portability | How easily you can open, modify, and view the files on computers using different operating systems, software and browsers. |
| Transparency | Allows the background color of an image to be “eliminated” or made transparent so that the background behind the image can be seen. |
| Inches | The standard unit of measurement for the United States and U.S. standard sized papers. |
| Letter size | is standard for most printers, resumes, and other common documents. |
| Pixels | The most common unit of measurement for computer screen display. Generally represented by one dot that is illuminated on a computer screen. |
| Points | The standard unit of measurement for typefaces. 1 point represents 1/72 of an inch. |
| Picas | One pica equals 1/6 of an inch. |
| resolution | is a measure of the amount of detail that is stored in a digital image. |
| Image Resolution | Resolution is measured in PPI, or pixels per inch |
| Monitors | low resolution devices, most display 72 ppi |
| Printers | resolution at which printers can print is measured in Dots Per Inch |
| Color Modes | a mathematical model that describes the way colors can be represented as numbers or percentages, typically with three or four values. |
| RGB Color | assigns an intensity value to each pixel ranging from 0 to 255 |
| CMYK Color | assigns a percentage value for each of the process inks. |
